Thomas made an interesting experiment where he baked in an standard household oven some PLA (and other filament) objects. It looks like you can improve the strength significantly with this simple method.

See the entire process and measurements in his video:

With change in strength, there is naturally some shrinkage and expansion in different axis.

Let us know in the comments if you have simillar experiences with heat treated PLA or simillar materials!
